Normal Lab Values Usmle 3r343b

I prefer the term "Typical" to describe laboratory values. Using the word "Normal" implies that someone falling outside of the given range is "Abnormal" ... and I do not think that is a term that a health care provider should present to their patients. I prefer to consider someone's laboratory values as "Typical" vs. "Atypical" rather than "Normal" vs. "Abnormal.” Thank you Alan Gault for that one! Typical “Normal” Laboratory Values that appear on the USMLE Step 1 provided by the NBME and formatted by [email protected].

*Included in the Biochemical Profile (SMA-12). By chance alone, at least one false-positive result is expected in almost half the people having 12 tests (SMA-12) and in two thirds of those having 20 tests (SMA-20). SMA-6 (6 tests) – bicarbonate, chloride, glucose, potassium, sodium, urea nitrogen SMA-12 (12 tests) – bicarbonate, calcium, chloride, cholesterol, creatinine, glucose, phosphatase (alkaline), potassium, sodium, transaminases (alanine and aspartate), urea nitrogen SMA-20 (20 tests) – protein (albumin), bicarbonate, bilirubin (direct and total), calcium, chloride, cholesterol, creatinine, gamma-glutamyltransferase, glucose, lactic dehydrogenase, magnesium, phosphatase (alkaline), potassium, protein (total), sodium, transaminases (alanine and aspartate), urea nitrogen, uric acid Typical “Normal” Laboratory Values that appear on the USMLE Step 1 provided by the NBME and formatted by [email protected].
